Books

Exchange Rate Misalignment: Concepts and Measurement for Developing Countries

Lawrence E. Hinkle and Peter J. Montiel, editors
Published by Oxford University Press
This book provides a comprehensive treatment of the conceptual and empirical issues relating to measuring exchange rate misalignment in developing countries. The aim is to provide policymakers and their advisers with a compendium of practical techniques for estimating equilibrium real exchange rates in settings where data, time, and professional capacity are limited.

The book assesses alternative empirical measures of the internal and external real exchange rates. It surveys the literature on estimating equilibrium exchange rates in both industrial and developing countries. It presents the currently available methodologies for empirically estimating the equilibrium exchange rate in developing countries, analyzing four of them in detail.

Social Capital: A Multifaceted Perspective

Partha Dasgupta and Ismail Serageldin, editors
The views on "social capital" are many and varied, and the concept remains too loosely defined to be usable in quantitative research into the character of societies. To explore the issues surrounding the idea of social capital, the World Bank convened a multidisciplinary workshop in April 1997. Many of the papers that resulted from that workshop are included in this volume, which is intended to provide a reasoned account of the current understanding of the concept. The volume covers both theoretical and empirical studies.

Development Issues in the 21st Century

Gudrun Kochendörfer-Lucius and Boris Pleskovic, editors
Published by the German Foundation for International Development

This volume contains articles presented at the 1998 Villa Borsig Winter Workshop, the first in a series intended to provide a forum for European researchers to contribute to early discussions in preparation for the World Bank's annual World Development Report. The workshops are sponsored by the Development Policy Forum of the German Foundation for International Development and the World Bank.

The workshop identified six trends that will define the institutional and policy matrix of sustainable development in the 21st century: a tendency toward globalization, continuing environmental change, demographic transition in developing countries, greater political participation and community involvement, increasing decentralization and the emergence of smaller economic clusters within (but also autonomous from) the nation state, and sweeping urbanization in the developing world.

Journal

The articles summarized below appear in the May issue of the World Bank Economic Review, vol. 13, no. 2.

Household Income and Child Schooling in Vietnam

Jere R. Behrman and James C. Knowles
The stronger are the associations between household income and child schooling, the lower is intergenerational social mobility and the less equal is opportunity. This article estimates the associations between household income and child schooling in Vietnam and finds that they are considerable. It also investigates some ways in which school fee policies relate to household income.

Benefit Incidence, Public Spending Reforms, and the Timing of Program Capture

Peter Lanjouw and Martin Ravallion
This article uses the geographic variation in 1993-94 household survey data for rural India to estimate the marginal odds of participating in schooling and antipoverty programs. The results suggest early capture of these programs by the nonpoor. The article shows that conventional methods for assessing benefit incidence underestimate both the gains to the poor from higher public outlays and the losses from cuts.

Does Informality Imply Segmentation in Urban Labor Markets? Evidence from Sectoral Transitions in Mexico

William F. Maloney
Using detailed panel data from Mexico to look at worker transitions between sectors, this article finds little evidence in favor of the traditional dualistic view of the relationship between formal and informal labor markets. The patterns of worker mobility do not suggest a rigid labor market or one segmented along the formal-informal division.

Tax Incidence in Madagascar: An Analysis Using Household Data

Stephen D. Younger, David E. Sahn, Steven Haggblade, and Paul A. Dorosh
This article asks who pays the taxes in Madagascar. Its main concern is to identify the progressivity of different taxes, based on the consumption and income patterns in a 1994 nationally representative survey. It finds that most taxes are progressive, meaning that wealthy households pay proportionately more relative to their expenditures than do poor households.

Genuine Savings Rates in Developing Countries

Kirk Hamilton and Michael Clemens
After developing the theory of genuine savings-traditional net savings less the value of resource depletion and environmental degradation plus the value of investment in human capital—this article presents empirical estimates for developing countries for 1970-93. It shows that genuine savings are negative in a wide range of countries, particularly in Sub-Saharan Africa.

Winners and Losers from the Privatization and Regulation of Utilities: Lessons from a General Equilibrium Model of Argentina

Omar Chisari, Antonio Estache, and Carlos Romero
Using a computable general equilibrium model, this article estimates the macroeconomic and distributional effects of the privatization and regulation of utilities in Argentina, begun in 1989. It finds that both privatization and effective regulation yield significant macroeconomic benefits. Gains from privatization accrue mainly to high-income classes, and those from effective regulation to low-income classes.

Determinants of Commercial Bank Interest Margins and Profitability: Some International Evidence

Asl1 Demirgüç-Kunt and Harry Huizinga
Using bank-level data for 80 countries in 1988-95, this article shows that differences in interest margins and bank profitability reflect a variety of determinants: bank characteristics, macroeconomic conditions, explicit and implicit bank taxation, deposit insurance regulation, overall financial structure, and underlying legal and institutional indicators.

Discussion, Technical, and Related Papers

Court Performance around the World: A Comparative Perspective

Maria Dakolias
Technical Paper 430

This paper describes and explains the performance of court systems in a sample of developing and industrial countries in order to provide data to those designing or evaluating reforms. It also shows areas in which international comparison of judicial performance can be fruitful and suggests indicators that can be used in such comparisons.

Health Expenditures, Services, and Outcomes in Africa: Basic Data and Cross-National Comparisons, 1990-1996

David H. Peters, Kami Kandola, A. Edward Elmendorf, and Gnanaraj Chellaraj
Despite remarkable improvements in the past 30 years, African countries still suffer from some of the worst health conditions in the world. To aid health planning and policy development in Africa, this paper presents national-level information on health expenditures, health service outputs, and health outcomes. By exploring gaps in the information available and potential uses of health information, the paper is also aimed at stimulating discussion on how better to monitor progress and use information for improved health outcomes in Africa.

Trade, Global Policy, and the Environment

Per G. Fredriksson, editor
Discussion Paper 402

This volume attempts to further the understanding of the empirical links between trade and the environment. Its 13 chapters, presented as papers at a World Bank conference in April 1998, focus on three main themes: the effects of trade liberalization and growth on the environment, the "pollution haven" hypothesis, and economic instruments for resolving global environmental problems.

Beyond the Center: Decentralizing the State

Shahid Javed Burki, Guillermo E. Perry, and William Dillinger
Latin American and Caribbean Studies

This report examines the effect of decentralization on the efficiency of public services, on equity, and on macroeconomic stability. It also addresses the issue of politics and notes that successful decentralization requires more than good rules. Those rules must be compatible with incentives. The report therefore looks at the broader set of rules that affect political behavior, focusing on electoral systems and political parties.

Adjustments after Speculative Attacks in Latin America and Asia: A Tale of Two Regions?

Guillermo E. Perry and Daniel Lederman
Latin America and the Caribbean Region Viewpoints

This paper compares the adjustment process in the aftermath of speculative attacks in six countries: Argentina, Brazil, Mexico, Indonesia, the Republic of Korea, and Thailand. Although all six came under the aegis of adjustment programs supported by international financial institutions, their experiences have differed. While the Mexican and Argentine crises of 1995, and even Brazil's adjustment after the October 1997 attack on its currency, were costly, the Asian crises have been deeper and the recovery of the real economy has been slower. The paper draws implications for policies to reduce the costs of the macroeconomic adjustment after currency crises.

Electronic Information and Data

A growing body of evidence suggests that world inequality is increasing, but the source of that increase has been unclear. Two World Bank initiatives have begun to shed light on this issue: recent research based on household survey data for more than 100 countries, and a new technique to graph and analyze income distribution.

World income distribution

Most estimates of the global distribution of income treat individuals as having the average income of their country. Such aggregations implicitly rank a poor American household above a richer Chinese household. To derive a "true" income distribution among individuals would require knowing their actual income (adjusted for price differences between countries). The lack of such data for most countries and the sheer size of the exercise compelled analysts to settle for approximations.

But household income data are now available for more than 90 percent of the world's population. The number of household surveys has increased, particularly in Africa, and political changes in China and the former Soviet Union have allowed compilation and release of survey data. A recent Bank study has taken advantage of the expanded pool of survey data, deriving and comparing world income distribution in 1988 and 1993.

The 1988 survey data cover 101 countries representing about 4.6 billion people, or almost 87 percent of the world's population. The 1993 surveys cover 119 countries—more than 90 percent of the population and about 95 percent of world GDP. As these shares suggest, the 61 countries not in the study are very small.

The increased coverage in Africa accounts for most of the difference in the number of countries between 1988 and 1993. In 1988 comparable household data were available for only 14 African countries. By 1993 a survey program launched by the World Bank in cooperation with African governments had raised the number of countries to 29—representing nearly three-quarters of Africa's population and almost 90 percent of regional GDP.

Most of the data used in the study come from four sources:

The study's findings show that world inequality is very high. In 1993 the richest 1 percent of the world's people received as much income as the poorest 59 percent. What explains this inequality? By far the biggest factor is a person's country: about 75-80 percent of world inequality is due to the differences in average income between countries. Only 20-25 percent is due to class-that is, income inequality within countries.

Even more disturbing is the finding that inequality is increasing. Between 1988 and 1993 the real income of the richest 5 percent of the world's people increased by 12 percent, while that of the poorest 5 percent fell by almost 25 percent. So the world is becoming increasingly segregated between rich and poor nations. Economic growth in poor and populous countries is crucial not only to alleviate poverty but also to reduce world inequality.

Two cautions about the results here: First, because countries often collect either income or expenditure data, the calculations are based on a mix of the two. Since poor countries tend to collect expenditure data, and since expenditure measures tend to be higher than income measures, the results here probably understate world inequality. Second, the results refer to income or expenditure flows and do not account for stocks of assets. Ignoring wealth also would be expected to underestimate inequality.

For more information about the research and the data sources used, contact Branko Milanovic at the World Bank's main address or at bmilanovic@worldbank.org. The findings of the research are reported in a paper by Milanovic, "True World Income Distribution, 1988 and 1993" (Policy Research Working Paper 2244). For copies, contact Patricia Sader at the Bank's main address or at psader@worldbank.org.

International income distribution

A new graphical and analytical technique has been developed to allow comparison of income distribution across countries or income groups and over time. This technique also allows comparison of income distributions for the same country in different years, and simulation of the effects of changes in policies or conditions. The main advantage of the technique is that it does not require large bodies of data and is relatively easy to use.

The results of one application of this technique, which is called quasi-exact polynomial interpolation, are illustrated in figure 1, below. The curves above the horizontal axis show the distribution of population by income level, while the curves below the axis show their income. The area between the horizontal axis and each outer curve equals one, distributed so that the areas within the curves correspond to shares in total population or income. The thicker lines show the overall distribution of population and income, and the lighter lines the distribution in three sets of countries: Latin America, the OECD countries, and China plus India ("Asia").

Figure 1 International income distribution

Nearly all "Asians" earn less than $6,000, while nearly all OECD citizens earn more than that. Latin America has the greatest inequality of the three, with some of its people receiving the lowest income and others the highest. The lower half of figure 1 shows that most of the income in the world goes to people earning more than $10,000, almost all of whom are in OECD countries.

Another use of the technique is to simulate the effects of changes in policies or conditions. Income distribution could be decomposed graphically and analytically by such factors as salary, transfers, and capital income to show the effects of changes in tax and poverty alleviation policies, for example.

Because each curve in figure 1 is based on aggregate data—for 10 decile groups—the curves might be expected to be relatively discontinuous, reflecting the "bar chart" type of initial distributions from which they were derived. The new technique, however, smooths curves from these discontinuous data through precise interpolation; it also allows restoration of exact values at the interval boundaries and minimizes deviation in between (hence the "quasi-exact"). The program is implemented in GINI ToolPak, which runs in Microsoft Excel.

For more information on the technique or for copies of the GINI ToolPak software, contact Yuri Dikhanov at the Bank's main address or at ydikhanov@worldbank.org.
